example 1
[0129] Instance 1, such as image 3 As shown, it includes terminal A (shared terminal), terminal B (shared terminal) and management cloud.
[0130] Step 1, Terminal A fragments the shared data, obtains the first set of multiple fragmented data and the second set of multiple fragmented data, and obtains data combination rules;
[0131] Step 2. Terminal A sends the first set of fragmented data, the second set of multiple fragmented data, and the storage location of each fragmented data to the management cloud, and sends the first standard information of the fragmented data to the management cloud. The cloud is used for the verification of the management cloud (here, the content of the first set of multiple fragmented data and the second set of multiple fragmented data is the relationship between inclusion and inclusion);
[0132] Step 3, the management cloud stores the first group and the second group of fragmented data in different storage clouds according to the corresponding...

[0139] Instance 2, such as Figure 4 As shown, it includes surveillance camera (sharing terminal), monitoring terminal (shared terminal, such as mobile phone) and management cloud.
[0140] Step 1, the monitoring terminal scans the QR code on the monitoring camera to obtain the network address of the monitoring camera;
[0141] Step 2, the network address of the monitoring camera at the monitoring end, and sending data splitting rules and start monitoring instructions to the monitoring camera;
[0142] Step 3: After receiving the command to start monitoring, the monitoring camera starts to record in real time, and when the data obtained from the recording reaches the predetermined size, the video data is fragmented according to the data splitting rules in step 2, and multiple fragments are obtained. data;
[0143] Step 4, the monitoring camera uploads a plurality of fragmented data to predetermined addresses respectively, which are respectively storage clouds A, B and F (whe...

Abstract
The invention provides a data sharing method and system based on multi-cloud storage, and relates to the technical field of the cloud. The data sharing method based on the multi-cloud storage provided by the invention comprises the following steps: firstly splitting shared data needing to be shared into multiple fragmented data by a sharing end, and respectively storing the fragmented data into at least two target storage clouds; accessing the target storage clouds to acquire all fragmented data when a shared end wants to acquire the shared data, and then forming the complete shared data by use of data synthesis rule obtained in advance, namely, accomplishing the sharing process of the data. In the sharing process, the fragmented data is respectively stored in at least two target storage clouds so as to prevent the third-party from directly acquiring all data; and the third-party is difficult to know the data synthesis rule, so that the fragmented data cannot form the complete shared data even the fragmented data are acquired, and the data security is guaranteed.
Description
technical field [0001] The present invention relates to the field of cloud technology, in particular to a data sharing method and system based on multi-cloud storage. Background technique [0002] Data sharing is to enable users who use different computers and different software in different places to read other people's data and perform various operations and analysis. [0003] The degree of data sharing reflects the information development level of a region or a country. The higher the degree of data sharing, the higher the level of information development. To achieve data sharing, a set of unified and statutory data exchange standards should be established first, and the data format should be standardized so that users can adopt the specified data standards as much as possible. [0004] The traditional data sharing method can only publish the data of one terminal to other terminals through the public terminal / public platform, but this sharing method is not safe enough fo...
